There was a site called shizm.com that had mp3 downloads with house music. There was a DJ mix there called Paul and Fran live at live life in Boston 2001-02-04 (I'm almost sure). The first track was a slow bass and a jazzy buildup. Is it possible to identify the track or perhaps even locate the entire file? I believe that the file name was livelife010204.mp3 from shizm.com and was a 1 hour DJ mix
Google's cached version of djhistory.com as of today 12.jan.2017 (main site down for maintenance) has a thread of people reminiscing about LIFE in Boston, and one of the contributors mentions a site slowtospeak , with some mp3s of the live LIFE sets, including the date you mention.
The name of the sound in my head is "Endzones" by the artist Modaji. https://www.discogs.com/Modaji-End-Zones/master/316646
